ProKennex has re-defined the arm-friendly racquet thanks to its Kinetic technology. The ProKennex Ki 10 (305g) 2018 is a great option for players that want to unleash power with plenty of control. The flex combined with a 16×19 string pattern and 100 square inch head size deliver crushing impact while Kinetic technology in the racquet’s head help to mitigate the impact it has on a player’s arm while delivering added power to each shot. Without losing any feel for the ball, Kinetic technology is made up of unique chambers in the racquet that have special ball-bearings to absorb and release energy from your swing. Tried, tested and proven, Kinetic technology is perfect for any players that experience arm pain. While this is under 11.5 oz. the Ki 10 (305g) plays well above its spec and can stand toe to toe with heavier frames. The Kinetic technology, 330 swingweight and overall maneuverability make it a great option for any players looking to swing freely from the baseline with added depth.Specs:Head Size: 100 sq. in. / 645 sq. cm.Length: 27 in.Strung Weight: 11.3 oz. / 320 g.Unstrung Weight: 10.7 oz. / 305 g.Strung Balance: 4 Pts.
